There's a lot of caveats to that.

First, that was absolutely the plan when they started shifting the Overton window in the 1980s. They didn't realize how important good faith is to democracy, and it's gotten more out of hand than they intended. Now you've got Dick Cheney, Rex Tillerson, and other 80s Republicans trying to rein it in.

Second, compromise goes both ways. Our agenda doesn't have to go out of the window. The neolibs will give the kids free school lunches to help defeat fascism. This doesn't mean that we try to jerk the Overton window so far the other way that it breaks and we lose to fascists. We can both compromise in good faith.

Third, those Republicans always think results are instant. Fire employees and if things don't break in a month, then they were clearly right! And when things go to shit in two years, well, there must be another reason. Don't make the same mistake with progressive changes. We need more than a 50/50 senate split with West Virginia included to be able to make big changes. Results aren't instant, and don't give up when they're not.
